AXK0414TN needle roller bearing

Jiaxing bearing manufacturing co. , LTD. , production of needle roller bearings, needle roller bearing is a cylindrical roller of roller bearings, relative to its diameter, roller is thin and long. This is called needle roller. Product features: needle bearing with fine and long roller ( Roller diameter D 5 mm or less, the L/D 2 or more. 5, L for roller length) , so the radial structure is compact, its inner diameter size and load capacity at the same time, with other types of bearing outside diameter is small, especially suitable for radial size by a limited amount of supporting result. According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway. These bearings can bear radial load only. Note: needle bearing bearing capacity big, apply to the installation of limited size of the supporting structure, journal as rolling surface hardening on the surface, bearing with force fit into the hole, need not again for axial positioning. Bearing before installation should be injected into the right amount of grease, under normal circumstances, after the assembly no longer BK type bearing lubrication for shaft neck without out of the bearing, encloses the seal effect, and can withstand the small axial winding.
